Everton are sweating over striker Dominic Calvert-Lewin's fitness.
The centre-forward has been absent since the end of August with a thigh problem, sustained during a game against Brighton.
The 24-year-old has experienced a set back in his recovery, per the Liverpool Echo.
Manager Rafa Benitez may be without Calvert-Lewin for another two to three months.
However, the club are hopeful he can be back sooner, but they are not looking to rush him either.
